What are explanatory variables in regression?
Explanatory (or independent) variables are variables such that changes in their value are thought to cause changes in the "dependent" variables.
Ann recorded the effects of watching television on physical fitness. Which of these is a response variable?
Variables of interest in an experiment (those that are measured or observed) are called response or dependent variables. Other variables in the experiment that affect the response and can be set or measured by the experimenter are called predictor, explanatory, or independent variables.Variable - not consistent or having a fixed pattern; liable to changePhysical fitness
What is the explanatory variable?
An explanatory variable is one which may be used to explain or predict changes in the values of another variable. There may be several explanatory variables.
What are Numerical and pictorial information about variables are called?
Analytical statistics
A researcher tries to explain or bring about resulting changes in the response variable by performing an experiment which introduces an explanatory variable?
Answer is True... Via ApexVs
What is an independent variable in statistics?
In a statistical model you have two kinds of variable. Response variables are the "outputs" of your model. Explanatory variables, on the other hand, are the "inputs" of your model. Response variables are dependent on the explanatory variables. Explanatory variable are independent of the response variables.Imagine you were trying to formulate a statistical model of your car's fuel economy. The "output" of your model is miles per gallon (or kilometres per litre). That's a dependent variable. "Inputs" into your model might be (for example) engine capacity, number of cylinders, tyre pressure, etc. These are your independent variables. That is, fuel economy may be, or is, (to be determined by the modelling) dependent on engine capacity and/or number of cylinders and/or tyre pressure, etc.

What does collinear in statistics?
Two or more explanatory variables are collinear when they have a linear relationship with each other. You are usually expected to remove at least one of the variables from your multiple regression analysis.
Kevin recorded the effects of violent video games on antisocial behavior. Which of these is a response variable?
Variables of interest in an experiment (those that are measured or observed) are called response or dependent variables. Other variables in the experiment that affect the response and can be set or measured by the experimenter are called predictor, explanatory, or independent variables. Antisocial behavior

When drawing a scatter diagram along which axis is the explanatory variable placed Along which axis is the response variable placed?
In a scatter diagram, the explanatory variable is typically placed along the x-axis, while the response variable is placed along the y-axis. This arrangement helps to visualize the relationship between the two variables, allowing for easier interpretation of how changes in the explanatory variable may influence the response variable.
What are response variable?
A response variable, also known as a dependent variable, is the outcome or measurement that researchers are interested in studying or predicting in an experiment or observational study. It is influenced by one or more independent variables (predictors or explanatory variables). For example, in a study examining the effect of fertilizer on plant growth, the height of the plants would be the response variable. Analyzing the response variable helps determine the relationship between it and the independent variables.

What is an explanatory study?
seeking to establish connections between events or variables
What is another name for independent variable?
independent variable called also predictor variables,explanatory variables,manipulated variables etc.
Is causation the focus of explanatory research?
Yes, causation is a central focus of explanatory research. Explanatory research aims to understand the relationships between variables and uncover the causes behind certain phenomena or outcomes. It seeks to explain why certain events occur and how variables are connected to each other.
